1 or 1/0 doesn't raise an exception

[Rohannes]

'Dive into Python' has a very memorable and interesting section on the
exact behaviour of 'and' and 'or' in Python:

http://diveintopython.org/power_of_introspection/and_or.html

> No: &, | (and ^, too) perform bitwise operations in Python, C and Java:

"In complete evaluation ... both expressions are always evaluated. To
obtain complete evaluation in Java, you use & rather than && ... and
use | in place of ||" - Walter Savitch, Absolute Java 2nd ed.

Although & IS the bitwise-AND operator in Java:

I guess it's a matter of context.
